Free Math Worksheets for Grade 1

This is a comprehensive collection of free printable math worksheets for grade 1, organized by topics such as addition, subtraction, place value, telling time, and counting money. They are randomly generated, printable from your browser, and include the answer key. The worksheets support any first grade math program, but have been specifically designed to match Math Mammoth grade 1 curriculum.

The worksheets are randomly generated each time you click on the links below. You can also get a new, different one just by refreshing the page in your browser (press F5).

You can print them directly from your browser window, but first check how it looks like in the "Print Preview". If the worksheet does not fit the page, adjust the margins, header, and footer in the Page Setup settings of your browser. Another option is to adjust the "scale" to 95% or 90% in the Print Preview. Some browsers and printers have "Print to fit" option, which will automatically scale the worksheet to fit the printable area.

All worksheets come with an answer key placed on the 2nd page of the file.

Two-Digit Addition

Students should be provided a 100-bead abacus or base ten blocks for these
two-digit addition problems. The problems can even involve a regrouping, or making a
new ten, but students are not solving the problems by writing the numbers under each
other (adding in columns). The idea is just to use the manipulative to add.
